| dc.description.abstract | We report the results of a search for the decay B 0 → X ( 3872 ) ( → J / ψ π + π − ) γ . The analysis is performed on a data sample corresponding to an integrated luminosity of 711 fb − 1 and containing 772 × 10 6 B ¯ B pairs, collected with the Belle detector at the KEKB asymmetric-energy e + e − collider running at the Υ ( 4 S ) resonance energy. We find no evidence for a signal and place an upper limit of B ( B 0 → X ( 3872 ) γ ) × B ( X ( 3872 ) → J / ψ π + π − ) < 5.1 × 10 − 7 at 90% confidence level. | en_US |
